es, residing at ston and State of North Carolina, have invented certain new and useful Improvements in Safety Stop-Motions for Speeder-Machmes; and I do declare the and exact description as will enable others skilled following to be a full, clear, of the invention, such in the art to which it appertains to make and use the same.

This invention relates to safety stop motions for speeder machines.

The primary object of the invention is to provide a means for automatically stopping a speeder machme when on e of the cone belts breaks and causes the respective lower cone to drop, thus preventing breaking and tanglmg.

the yarn from Another object of the invention is to generally improve upon devices by the provision of a compar of this nature atively simple,

strong, durable and inexpensive construction,

pose for which it is designer one which will be efficient and reliable in operation, and well adapted to the pur With these and other objects in view, the

invention consists of certain novel features of construction, and the combination and arrangement of parts as will fully described and claimed.

In the similar reference characters parts throughout the several Figure 1 is a conventional be hereinafter accompanying drawings in which designate like views, representation of a speeder machine, showing a device conwith applied thereto, said device position, and

Fig. 2 is a. similar view this invention belng 1n set of a machine showing the device in actuated position.

Referring more particularly to the drawings, the numeral 1 cone of a speeder machine, 2

designates the upper the lower cone thereof which is driven from the upper cone by means of a belt 3. In order to maintain the belt 3 at all times tight, the cone 2 is more or less supported by the belt so that in case of the breakage of the belt, the cone 2 will drop. The cone 1 is dri being supplied to the entlr means of a belt 4 which en ven, the power e machine by gages a guide Patented Sept. 28, 1920. Serial No. 315,933.

machine is not in 01 end of the lever 9 is forked as at 10 and this forked portion straddles the rod 7 and engages a collar 11 carried by the rod so as to shift the latter when said lever is rocked. The the lever 8 is pivotally con nected to one end of a bar 12 which will hereinafter be referred to as a trigger. The other end of the trigger 12 is bent laterally as at 13, and the free end of this laterally bent portion carries an arm 14 which engages a resilient brake bar 15 to hold the same out of engagement with a pulley 16 carried by the shaft of the upper cone. coil spring 17 connected at one end to the brake bar 15 and at its other end to the o or or other stationary part of the machine exerts its tension so as to move the brake bar 15 into frictional engagement with the pulley 16 when the arm 14 is disen aged from the bar 15.

crewed or otherwise fixed to the floor or othermovable part ofthe speeder machine is a bracket 18, the latter forming a support for a lever 19 which is fulcrumed intermediate of its ends and provided at one end with a post 20 disposed directly beneath the lower cone 2 so as'to be engaged by the cone when the same drops. The other end of the lever 19 carries a plate 21 having a guide opening 22 therein to receive and guide the'trigger 12, and a hook-shaped lug or arm 23 poistioned so as to engage a stop 24 fixed to the floor of the speeder machine and thereby limit the movement of the lever. The trigger 12 is provided with a notch 25 which is adapted to engage the stop 24 and hold said trigger in set position against the tension of. a spring 26 connected at one end to the trigger and at its other end to the floor of the machine.

lVhen the machine is running, the normal position of the parts of the stop motion is inengage the post 20.

' the movement of this dicated in Fig. 1 of the drawings. By this it will be seen that the lever 19 having the trigger 12 resting upon and slidably connected to one end is over-balanced at this end so that the trigger also rests upon the stop 24 with its notch 25 engaged with the stop and the spring 26 being under considerable tension. The arm 14 is also in engagement with the brake bar 15 holding it out of engagement with the pulley 16 and putting the spring 17 under tension. Should the belt 3 break, the cone 2'will necessarily drop to the position shown in Fig. 2 of the drawings and The weight of the cone resting upon the lever 19 will overbalance the weight carried at the other end of said lever and bring the same to its other position. This movement raises the trigger 12 so that its notch 25 is disengaged from the stop 24. The trigger 12 is then free to slide and such a motion takes placeunder the pres sure of the spring 26. When the trigger 12 slides, the lever 8 is necessarily rocked an lever shifts the rod 7 so as to shift the belt 4 from the drive pulley 5 to the idle pulley 6. Power is thus removed from the machine. When the trigger 12 is shifted the arm 14 carried by the same will slide from under the bar 15, and the latter will be moved into engagement with the pulley 16 under the action of its spring 17 The motion of the cone 1 will therefore be immediately arrested, and the yarn contained on this and the other cone 2 willnot-be subjected to beingbroken or tangled. The machine cannot be started until the belt 3 is mended or replaced by a new belt and the stopping mechanism set in the position shown in Fig. 1.

' The trigger 12 is provided with a notch 27 adapted to engage the stop 24 and hold the trigger in released position. There may be times when such a locking means is desirable.

From the foregoing description taken in connection with the accompanying drawings, the construction, use and operation of the invention will be readily understood.

Various changes in form,'proportion and in the minor details of construction may be resorted to without departing from the spirit machine,

of the invention as defined in the appended claims. 7

WVhat is claimed is:

1. The combination with a speeder machine, of a lever fulcrumed to a stationary part of the machine and operatively connected to the belt shifting rod thereof, a brake for one of the upper cones of the machine, a stop fixed to a stationary part of the a. trigger connected to said lever and engageable with said brake, said trigger being engageable with said stop when in set position to hold said lever and said brake inoperative, and a second lever fulcrumed to a stationary part of the machine and engageable with said trigger to release the latter and permit said to shift and said brake to be applied, said second lever being positioned beneath and adapted to be engaged by the corresponding lower cone of the machine upon breaking of the belt connecting said cones.

2. The combination with a speeder machine, of a lever fulcrumed to a stationary part of the machine and operatively connected with thebelt shifting rod thereof, a brake for one of the upper cones of the machine, a stop fixed to a stationary part of the machine, a second lever fulcrumed to a stationary part of the machine beneath the corresponding lower cone thereof and carrying a guide and a lug atone of its ends, said lug being positioned for engagement with said stop when said second lever is in one of its positions, a slidable trigger extending through said guide and having one end connected to said first lever, said trigger engaging said stop when in set position, m m carried by said trigger and when the latter is inset position engaging said brake to hold the same inoperative, a spring for applying first lever and said rod said brake when released, and another spring I WALTER F.
